The idea is based on research showing that people have unique feet and ways of walking. Sensors in the footpad collect data and check the patterns.
The lab is a partnership with Autonomous ID, a Canadian company that is relocating to the U.S. President Todd Gray says he saw the potential in a maternity ward decorated with representations of baby feet along a wall.
One expert says the technology sounds impressive, but it could raise privacy questions.
Attorney Lee Tien with the Electronic Frontier Foundation says any biometric device is a potential tracking device.
